Fabrication of obturator prostheses does not require a special ability to fabricate a prosthesis extension into a defect or an arbitrary extension of a prosthesis into a defect. Fabrication of an obturator prosthesis depends on the application of basic prosthodontic principles that are used in the treatment of patients without maxillary defects. Some principles must be modified because of the defect and the character and position of the remaining structures. The defect, in conjunction with the remaining structures, must be used to provide support, retention, and stability of an obturator prosthesis. If basic prosthodontic principles are applied the size and extension of the obturator will be determined, and the extensive variation so commonly seen in obturators will be minimized. Acceptable prosthodontic care for the patient with the acquired maxillary defect should include cautious prosthesis design combined with routine maintenance care to provide comfort, function, cosmetics, and minimal change to the compromised remaining structures.
赝复体的制作并不需要将赝复体延伸至缺损部位或随意延伸至缺损部位的特殊制作能力。赝复体的制作取决于应用于治疗无上颌骨缺损患者的基本口腔修复学原则。由于缺损以及剩余结构的特征和位置，一些原则必须进行修改。缺损与剩余结构相结合，必须用于为赝复体提供支持、固位和稳定。如果应用基本的口腔修复学原则，将确定赝复体的大小和延伸范围，并且赝复体中常见的广泛差异将降至最低。对获得性上颌骨缺损患者进行可接受的口腔修复治疗应包括谨慎的赝复体设计，并结合常规维护护理，以提供舒适度、功能、美观，并尽量减少对受损剩余结构的改变。
